London: Southampton have signed Serbian midfielder Dusan Tadic from Dutch club FC Twente, the Premier League club announced on Tuesday.
Tadic, 25, joins Saints for an undisclosed fee, reported to be in excess of £8 million ($13.7m, 10 miilion euros) and becomes new manager Ronald Koeman`s first signing.
Southampton are looking to rebuild following the departure of England internationals Luke Shaw, Adam Lallana and Rickie Lambert, in the wake of manager Mauricio Pochettino jumping ship to join Tottenham.
Tadic said: "It is a really nice feeling, this is a really nice club of which I have heard a lot of good things about.
"I have already seen the beautiful training centre and there are lots of nice people that work here including the coaches, so I am really happy to be here."
An attacking midfielder, Tadic scored 16 goals in 33 league games last season as Twente finished third behind Ajax and Koeman`s Feyenoord.
Koeman feels Tadic`s arrival will act as a "great signal" of Southampton`s intent to move forward following last season`s top-10 finish and the departure of so many key players.
"It was very important to get this signing done - not only for me, but for the rest of the squad and for our fans. It`s fantastic news," he said.
"We have lost some good players, but we want to continue the ambition and philosophy of the club, so it is a great signal to have brought in our first player."
Southampton have also been linked with Italian striker Graziano Pelle from Feyenoord and Lorient`s Gabon international defender Bruno Ecuele Manga, seen as the perfect replacement for wantaway Dejan Lovren, who is set to join the exodus to Liverpool.
